Hi,

I got an error message "value cannot be null. Parameter name: container", after the following actions:

(1) Duplicating a chain of mechanical models and static structural blocks, from a solved models.

(2) Edit one of the mechanical models (Block E) in DesignModeler (move two bodies to be exact).

(3) Update and re-read upstream data on the duplicated static structural model (Block F).

(4) Got the error "value cannot be null. Parameter name: container"

Attached are the schematics of my workbench and the error message. Block E,G,F are duplicates from Block B,C,D respectively.

Hi

I would start to delete system F.

Add then a new static and not a copy of system D, and then connect system E and G to it (new static system).

Also read through this that might help:

Yes, creating a new system and reconnect it to E&G works, but that would require me to re-assign all the bodies and surfaces in boundary conditions, which is time consuming.
I am trying to avoid that by duplicating the whole chain of blocks. Do you have any further advise on that?
